This paper shows the results of a study carried out by the IEEE-Education Society Spanish Chapter on the state of implementation of the Bologna process in engineering degrees along Spain and the opinion of teachers about the main aspects of this implementation. These include the implementation of new learning methodologies (problem-based learning, collaborative learning, project-based learning, etc.), resources, assessment criteria, workload of students and teachers, the support of each university for the EHEA implementation, and the general satisfaction (or not) about the EHEA. The aim of this paper to contribute to a reflexive debate, not only in Spain but also in the international community, about the advantages and drawbacks of the EHEA implementation in engineering education.
